Cosmotalks Datasette 15 ⭐
Database app of links to 4,273 online talks by cosmology researchers presenting their work to others in the field. Database is hosted on Google Cloud Run at:
Sfof 13 ⭐
SFoF is a friends-of-friends galaxy cluster detection algorithm that operates in either spectroscopic or photometric redshift space. The linking parameters, both transverse and along the line-of-sight, change as a function of redshift to account for selection effects. The code is written in C++ and implements OMP to loop through the photometric redshift bins.
Zeldovich Plt 12 ⭐
Generates initial conditions for cosmological N-body simulations, optionally applying Particle Linear Theory corrections.
